Robertshaw 712-020 Nonlockout Dual Pilot Ignition System

Product Description

The ROBERTSHAW 712-020 is a nonlockout dual pilot flame rectification ignition system designed for intermittent pilot ignition applications in gas-fired heating equipment. Part of the Uni-Line 712 series, it uses solid-state logic and flame sensing to deliver automatic sequencing that confirms proper pilot operation before opening the main gas valve. The system handles natural gas applications and is engineered for reliable, repeatable ignition cycles without entering a lockout state after failed ignition attempts. Licensed HVAC technicians and gas appliance service professionals are the primary installers.

The 712-020 fits a broad range of residential and light commercial gas furnace applications. The 712 series platform supports up to 720,000 BTU/h on natural gas, depending on the gas valve type paired with the control. Four gas valve configurations are available across the 712 series to accommodate varying furnace designs. Because this unit is the nonlockout variant, it continues to attempt ignition without imposing a timed lockout period, making it suitable for installations where nuisance lockouts are a service concern. Consult the Robertshaw 712 series ordering chart to confirm the correct gas valve pairing for the specific application.

Key Features

• Flame rectification with solid-state logic ensures accurate pilot flame sensing before sequencing to main burner operation
• Nonlockout design allows continuous ignition retry cycles without entering a lockout delay
• Dual pilot capability supports two-pilot burner configurations
• Automatic sequencing provides controlled, repeatable ignition without manual reset intervention
• Compatible with up to four gas valve types across the 712 series platform for broad furnace fitment
• Includes complete installation instructions and troubleshooting reference documentation

Compatibility

Designed as an OEM-style replacement for intermittent pilot ignition systems in residential and light commercial gas furnaces requiring flame rectification control. Natural gas applications up to 720,000 BTU/h are supported depending on the gas valve model selected. Refer to the Robertshaw 712 series ordering chart for gas valve type compatibility before installation.

Installation Notes

Installation of gas ignition controls must be performed by a licensed HVAC technician or qualified gas appliance service professional in accordance with the International Fuel Gas Code and applicable local codes. Shut off gas supply and disconnect electrical power to the appliance before removing the existing control. Verify gas valve type compatibility against the 712 series ordering chart before wiring the new control. Follow the included wiring diagram and troubleshooting guide; do not substitute components or modify the control circuit.
